Abstract

In an increasingly competitive educational landscape, many institutions are seeking technologies that enhance performance. An academic information system is a system developed to manage academic data using computer technology, transforming academic processes into useful information. This research aims to design a web-based academic information system at Holistic Children Center Elementary School. Currently, the management of academic data at the school is conducted manually using books and Microsoft Excel, which is prone to data loss and inefficient in tracking academic information. The implementation of an academic information system with a centralized database method is expected to improve the effectiveness and efficiency of academic data management and support the enhancement of the school's accreditation. The research methods employed include direct observation, interviews with school officials, and literature studies to obtain relevant theories and methods. The results indicate that the designed academic information system can manage data centrally and structurally, facilitating information presentation for teachers, students, and parents. Additionally, this system can enhance the school's reputation through more organized and integrated data management and simplify the tracking and documentation of alumni.

Abstract

This study examines the LSTM-based model for processing spam in text data. Spam poses several dangers and risks, both for individuals and organizations. Spam can be a nuisance that hampers both individual and organizational productivity. Much spam contains fraudulent or phishing attempts to obtain sensitive information. Spam detection using deep learning involves the utilization of algorithms and deep neural network models to accurately classify messages as either spam or not spam. Typically, spam detection systems use a combination of these methods to improve the accuracy of identifying spam messages. This study applies the Bi-LSTM deep learning model to sequentially process text (sequencing). The performance of the model is determined based on the loss and accuracy. The data used are the Spam SMS and Spam Email datasets. The test results show that the Bi-LSTM model demonstrates better performance on all tested datasets. Bi-LSTM is able to capture textual patterns from both the context and the text itself, as it can combine information from both directions. The test results prove that the Bi-LSTM model is more effective in text comprehension. So we need to use Snort to maintain network security. Snort is a useful software for observing activity in a computer network. Snort can be used as a lightweight Network Intrusion Detection System (NIDS). Detection is carried out based on the rules that have been described by the administrator in the directory rules contained in the configuration file. Snort can analyze real time alerts, where the mechanism for entering alerts can be in the form of a user syslog, file or through a database. So we can detect attacks on computer networks early.

Abstract

Airplane transportation has many advantages compared to other means of transportation, where this means of transportation is able to cover long distances in a short time. Besides having advantages, of course, air transportation often experiences flight delays which can be caused by several things, including delayed flights due to late arrival (Arrival Delay), delays of the airline itself (Carrier Delay), previously late arrivals (Late Aircraft Delay), air traffic congestion (Nas Delay), security issues (Security Delay) and weather conditions (Weather Delay) The tests carried out were 101,315 US flight delay data from 2017 to 2022. By using the Machine Learning method, the results obtained were that the largest flight delays were caused by late arrivals, namely 386,124,672, where the largest flight delays were by airlines. The airline, namely Southwest Airlines, is 61,474,379 of the total airlines, which is 20, and the biggest departure delay is at Chicago O'Hare International airport, which is in the city of Chicago, IL province, which is 20,912,928 of the total airport, which is 596. This research aims to predict future flights by analyzing current flight data, so that future flights can be better by overcoming or avoiding previous flight delay problems

Abstract

This community service activity aims to improve the logic skills of students at SDN 060934 through the application of multimedia-based educational games. By identifying the problems students face in understanding logic concepts, the program is designed to provide an engaging and interactive learning experience. The implementation of activities includes socialization, training, and the use of educational games that have been selected based on student needs. Evaluation results showed a significant improvement in students' logic skills, with the average pre-test score increasing from 65 to 85 in the post-test. In addition, students also reported a more enjoyable learning experience and higher motivation to learn. Although challenges related to technological infrastructure still need to be overcome, this activity proves that educational games can be effectively integrated in the learning process to support the development of critical thinking skills among students. It is recommended that this method be applied more widely in other schools in an effort to improve the quality of education in Indonesia

Abstract

Currently, there are still many corporate agencies that do not use computerized systems, the same goes for PT. Damai Alam Sejahtera Lobu Siregar, Siborong-borong District. Financial System at PT. The existing Peace of Alam Sejahtera Lobu Sigerar is no longer in accordance with current developments, so it is still not well structured. Especially for financial systems, in this system what is processed is income, expenditure and report data. Systems can be defined in two groups of approaches, the first system approach places more emphasis on procedures, the second system approach places more emphasis on elements or components. The problem currently occurring is the slow processing of data, the reports produced must go through unstructured data collection. In the information system to fulfill this task, we will explain how to design a web-based financial information system. In designing this system, Entity Relational Diagrams and Data Flow Diagrams are used, while data collection uses observation, interviews, and literature studies. This website was created using the PHP programming language and MySQL as the database. It is hoped that this application system will further help Admin performance in PT finance. Peace Alam Sejahtera Lobu Siregar has become more effective and efficient.
